* Add handler for space-delimited lists

* This needs attention, however. The INI writer has no way to know a list with spaces is a list; this happens in the value conversion functions.
* Add type_hint member to INIData structure. At some point support with be added for all INIVAL_TYPE_* defines. Right now it's only used with arrays.
* Zero out line buffer in ini_open after each iteration
* Do not strip raw INI data. Let the conversion functions handle it
* Add spaces to key value pairs in rendered INI output.

* Add ini_getvar_TYPE() functions

* These replace the functionality of static conv_TYPE() functions in delivery.c
* Add support for missing types: U/CHAR, U/SHORT, STRLIST

* ini_getval: expand template variables immediately before processing the output

* Strip leading space to avoid issues with string comparisons against the result

* ini_getval: Return copies, not the original.

* This forces one to use ini_setval to replace/append values to the data array(s). It's safer this way.

* fix_tox_conf(): Use ini_getval and ini_setval instead of modifying the original pointers directly

* Tests: Free resources

* Replace ini_getval(), ini_getval_required() and conv_*() usage

* Now using ini_getval_TYPE() functions and ini_setval()
* Remove unused helper functions and variables

* download() returns long, not int

* actions: update apt cache

* Initial commit of unit tests [WIP]

* Address shortcomings and bugs flushed out by unit tests

* Enable unit testing in CI workflow

* Enable verbose ctests

* Handle lack of __FILE_NAME__ define

* Only podman support `run --arch` argument

* Skip docker build testing if CI system cannot pull an image

* Remove errant call to puts()

* Identify local repo user

* Fix missing xmllint

* NULL terminate arrays

* Fix filename assignment in is_url mode

* Break loop when expected lines are exhausted

* strcmp_array expects NULL terminated array. Iterating by size in this case passes NULL to strcmp leading to an invalid read

* Remove debug printf statements

* Disable a few warnings for tests

* Workaround for ctest junit xml truncation

* Update checkout@v4

* Prevent false-positive result

* Return zero on error

* Fix strlist_remove function

* Value argument can be constant

* Fix test to match changes to startswith and endswith

* Add test_ini.c

* Fix redaction code to accept NULL pointers in array

* And let the caller specify the length of the array of strings to redact.

* Redactions now occur directly on authentication strings rather than their command line arguments

* Fix BUILD_TESTING_DEBUG

* Adds missing -D argument
